Reduced distal embolization with transluminal extraction atherectomy compared to balloon angioplasty for saphenous vein graft disease.

摘要: Extraction atherectomy utilizes suction aspiration as an attempt to limit distal emboll during atherectomy. We sought test the hypothesis that extraction produces less embolization than balloon angioplasty when treating saphenous vein grafts. Among 163 consecutive, nonrandomized patients, 103 patients underwent transluminal catheter (TEC)® with or without adjunctive angioplasty, and 60 had conventional angioplasty. Both groups showed comparably high procedural success rates (TEC 90.3%, 83.3%, P = NS). TEC cases a significantly lower incidence of angiographic embolization, compared (3.9% vs. 16.7%, 0.005). In evidence thrombus in grafts, maintained (5.6% 31.8%, 0.004). There were no statistical differences between two regarding other procedure-related complications, including death, myocardial infarction, emergency coronary artery bypass grafting. appears have particularly presence angiographically apparent thrombus. © 1996 Wiley-Liss, Inc.
